Step-by-step explanation:
Given the following :
Number of visitors on Friday = 3,260
Number increased by 15% on Saturday
Projected percentage increase on Saturday = 20%
Actual percentage increase in number of visitors = 15%
Number of visitors on Saturday :
(100 + 15)% × 3260
115% * 3260
(115/100) * 3260
= 3749 visitors
Projected percentage increase = 20%
Projected number:
((100 + 20)% * 3260
120% * 3260
(120/100) * 3260
= 3912
Difference : (3912 - 3749) = 163
